Generation of high-density biskyrmions by electric current

Spintronics: Generation of magnetic biskyrmions by electric current Electric current can generate and control the density of magnetic biskyrmions in a centrosymmetric MnNiGa alloy at room temperature. Skyrmions are chiral spin textures whose spins point in all directions wrapping a sphere, making th...
